What is the importance of CO2, H2CO3, and HCO3- in maintaining blood at pH 7.4? Also, what page in the book is this information?
Thank you!

Re: Importance of compounds in Blood
This is the bicarbonate buffering system. The equilibria involved:
CO2+H2O --> H2CO3 (or reversed)
H2CO3+H2O--> H3O+ + HCO3-
With too many hydronium ions in blood, H3O+ will react with HCO3- and form water and H2CO3.
Too few hydronium ions, H2CO3 will react to form H3O+ and HCO3-
This helps to maintain the pH.
